“…However, the case of the light waveguided along the PC's layers is also of great interest. The dispersion of the guided modes in single transversely-magnetized single film depends linearly on the magnetization [21][22][23][24][25]. A similar effect in transversely-magnetized PC's layers is expected.…”

Abstract. We present the study of the waveguide modes of one-dimensional magnetic photonic crystals with in-plane-magnetized layers. There is a magneto-optical effect of nonreciprocity for the TM-modes propagating along the layers perpendicularly to the magnetization. Due to the non-reciprocity the phase velocity of the modes changes with magnetization reversal. Comparison of the effect in the non-magnetic photonic crystal with additional magnetic layer on top and a magnetophotonic crystal with altering magnetic layers shows that the effect is greater in the first case due to the higher asymmetry of the claddings of the magnetic layer. This effect is important for the light modulation with external magnetic field in waveguide structures and may be used for design of novel types of the magneto-optical devices, sensors of magnetic field or biosensors.

“…It should be emphasized here, that on the contrary to the conventional MO waveguides with in-plane magnetization [17], modes conversion for the considered structure is largely due to the leaking nature of the quasi-guided modes in the dielectric slab. When the thickness of the dielectric film is appropriate for the propagation of To conclude, we have studied optical properties of bilayered system consisting of metal and dielectric parts, metallic plate being perforated with the periodic hole arrays and dielectric plate being magnetized in polar geometry.…”

We report on significant enhancement of the magnetooptical effects in gyrotropic systems of a metallic film perforated by subwavelength hole arrays and a uniform dielectric film magnetized perpendicular to its plane. Calculations, based on a rigorous coupled-wave analysis, demonstrate the Faraday and Kerr effect spectra having several resonance peaks in the near infrared range, some of them coinciding with transmittance peaks. Qualitative analysis revealed that magnetic polaritons being coupled magnetic-film waveguiding modes with surface plasmons play a crucial role in the observed effect. At the same time, substantial MO effect enhancement can be achieved in some nanostructured materials owing to the materials' interesting optical properties inherent to their nanoscaled

“…Magneto-optic influence The longitudinal magneto-optic effect is selected here in order to exploit the weakly guiding approximation, E 0, and to couple E to E. A description of the magneto-optic influence, without the nonlinearity, is arrived at from the basic equations V(EmE)0 (1) V2EV(VE)+CmEO (2) For the selected here, the differential equation, coupling E, to E, , is4,1°V…”

Extrinsic and intrinsic nonlinear magneto-optics is introduced through the use oflayered structures. Longitudinal magneto optic configurations are selected to promote the maximum coupling of field components. In the extrinsic calculations, linear magneto-optic layers are deployed with varying degrees of complexity in structures that have components that can become optically nonlinear. The properties of spatial solitons are investigated theoretically using a Lagrangian variational procedure. Interesting arrangements are discussed for general polarization interaction based on a magnetic field distribution that varies both along and transversely to the propagation direction. Finally, intrinsic nonlinear magneto-optics is briefly discussed, which uses a photomduced nonlinear Faraday effect.
